Water-Lubricated Sintered Bronze Journal Bearings—Theoretical and Experimental Research

Abstrakt

Water lubricated bearings are used from many years in shipbuilding, hydro power and other industries because of their advantages such as: extensive serviceable life, low coefficient of friction, longevity of shaft sleeve, good abrasion resistance, low maintenance required, unit simplicity, no danger of pollution and low price. Various types of water lubricated sliding bearings have been tested at the Technical University of Gdansk - stiff composite bearings, ceramic bearings, as well as elastic polymer ones. It was unequivocally determined that a properly designed hydrodynamic water lubricated journal bearing may function under hydrodynamic regime in the conditions of typical loads and speeds found in practical applications. In this paper, the authors present an attempt at researching the possibility of more extensive use of other stiff bush bearings, represented by bronze bush bearings. The aim of the research was to investigate stiff metal bearings, as solutions offering theoretically greater load bearing capacity than comparable elastic bearings, capable of replacing typical polymer and rubber bearings in certain applications. Based on the conducted research, it can be concluded that bronze bearings may constitute an interesting alternative to non-metallic bearings. Although they require hardened journal surface, they offer a greater load bearing capacity, durability and lower movement resistance levels. These bearings are particularly advantegous when used with journals of relatively small diameters working under heavy loads.
